Linux Disable / Remove All NFS Services

byVivek GiteonAugust 16, 2009

NFS was not designed with security in mind, and has a number of weaknesses, both in terms of the protocol itself and because any NFS installation must expose several daemons, running on both servers and clients, to network attack. I use my CentOS based server only to server web pages and nothing else. How do I disable NFS services under RHEL / CentOS / Fedora Linux?

You can easily disable NFS, which is a commonly used for sharing data and files between machines. However, its use opens many potential security holes. If NFS is not needed, improve the security by removing and disabling NFS. Open a command-line terminal (select Applications > Accessories > Terminal), and then type:# chkconfig nfslock off # chkconfig rpcgssd off # chkconfig rpcidmapd off # chkconfig portmap off # chkconfig nfs off Delete nfs-utils and portmap packages using the yum command:# yum remove portmap nfs-utils

my hp 4050n ntwroek printer doesn’t work with large images and certain pdf files in linux.. windows 7 it works flawlessly. I was impressed with Ubuntu’s printing , but it isn’t up to windows spec. It’s also a lot slower with my ntwroek printer.
